The Duchess of Cambridge gets to wear pretty things all the time β an engagement ring from the late Princess Diana, gorgeous designer dresses and, of course, the literal crown jewels.
But thereβs one thing you wonβt see Kate Middleton wearing while sheβs out and about attending royal engagements: bright nail polish on her fingernails.
βThe royal ladies always wear natural nail polish because very bright, especially red, is seen as rather vulgar,β Diana Mather, director and senior tutor at The English Manner, an international protocol, etiquette and hospitality consultancy firm in the U.K., told HuffPost.
βIn the old days prostitutes and courtesans wore red nail varnish (as it was called then) and ladies didnβt want to be associated with anything like that, so they wore understated colors,β Mather said. βRoyal ladies always keep their nails beautifully manicured, but if by some unfortunate mishap a nail gets chipped when out in public, it is much less visible if it is a natural shade.β
William Hanson, a British etiquette coach and expert, agreed and said that brightly colored nails are seen as βtartyβ by the British.
βNothing about any outfit any member of royalty wears should distract from the duty at hand,β he said.

Grant Harrold, an etiquette expert who now runs a Twitter, YouTube and website called βThe Royal Butler,β echoed Hansonβs thoughts.
βThe family would certainly not wear any form of product or makeup that will draw the wrong attention,β he said.
βHer Majesty the Queen wears a neutral polish, showing that royals do indeed wear nail polish, but opt for subtle and neutral colors keeping with tradition and not the latest fashion item.β
Mather said that Queen Elizabeth II is a fan of the βBallet Slippersβ polish from Essie, which you can purchase here for $9. Middleton reportedly wore a similar shade for her 2011 wedding to Prince William.

Middleton went with a similar, understated manicure for her engagement announcement photos with Prince William:


Throughout her time in the public eye, the Duchess of Cambridge has also kept her nails unvarnished or worn a lighter shade of polish at events:




Now, this news doesnβt mean that Middleton hasnβt ever worn bright nail polish before (she hasnβt been a royal her entire life). And weβve seen her wear red nail polish on her toes at a dinner at Claridgeβs in 2012.

And more recently she wore a similar red nail polish color on her toes earlier this year to a reception at ClΓ€rchens Ballhaus in Berlin, Germany.

Though it seems that royals wouldnβt necessarily wear bright nail polish on their toes, Mather offered an explained for Middletonβs choice.
βThe correct dress code states that toes should not be on display, but that rule is more relaxed in the 21st century, so perhaps the Duchess of Cambridge likes to be a bit more adventurous where her toes are concerned,β Mather said.
Just donβt count on Kate wearing bright blue or a sparkly pink polish on her fingernails any time soon (unless Princess Charlotte is able to convince her!)
